sock it to

Deliver a physical blow, forceful comment, or reprimand to, as in The judge often socks it to the jury in a murder case. This idiom uses sock in the sense of “strike hard.” It is also put as an imperative, as in Sock it to them, kid! or Sock it to me!, which is sometimes used to give encouragement but can also have sexual overtones.
